TORONTO - October 28, 2004 - IMAX Corporation (NASDAQ: IMAX; TSX: IMX) today
reported net earnings of $0.05 per diluted share for the three months ended
September 30, 2004, significantly ahead of management's guidance for a breakeven
quarter and the First Call mean of $0.01. This compares to a net loss of $0.07
per diluted share for the three months ended September 30, 2003. Excluding a
half-cent gain from discontinued operations, earnings from continued operations
were $0.04 in the third quarter of this year, as compared to a loss from
continued operations of $0.07 in the year-ago quarter.

The Company's consolidated revenues were $31.8 million for the third quarter
2004, compared to $21.2 million reported for the prior year period. IMAX Systems
revenue was $21.3 million versus $11.5 million in the prior year period, as the
Company recognized revenue on six theatre systems versus one in the third
quarter of 2003. Film revenue was $6.1 million versus $5.3 million in the same
period last year, and Theatre Operations revenue increased to $3.7 million from
$3.4 million. Other revenues decreased to $0.8 million in the third quarter of
2004 from $1.1 million in the same period last year. The Company also increased
its cash position to $20.7 million at the end of September from $17.0 million at
the end of June.

                                                                           .../2

"In the third quarter, we not only met our financial goals, with net earnings,
revenues and cash beating expectations, but we also continued to hit our
strategic goals, demonstrating strong progress towards our objective of making
IMAX(R) theatres synonymous with a premium-priced destination in the commercial
entertainment marketplace," said IMAX Co-Chief Executive Officers Richard L
Gelfond and Bradley J. Wechsler, "Our financial results are now starting to
reflect the traction we are seeing in the commercial exhibition marketplace and
we believe we are on track to meet our previously stated goal of earnings for
the full year of $0.25 per share, before refinancing costs of $0.02 per share."

The Company reached agreement for the sale or lease of 15 theatre systems in the
September quarter, marking its best quarter for signings since the fourth
quarter of 1997. These signings, which have a total value of $21.9 million,
represent a 200% increase in signings versus the third quarter of last year and
a significant acceleration from the four system signings reported in the second
quarter of the year and six signings reported in the first quarter. For the
first nine months of the year, the Company reached agreement for the sale or
lease of 25 theatre systems, as many as were signed in the full year 2003. These
third quarter signings represent a 39% increase from the 18 systems signings
reported for the comparable nine-month period in 2003, and move the Company
closer to its stated target of 30-35 signings for the full year.

Signings during the third quarter included agreements with three of the world's
largest exhibitors, National Amusements Inc., Cinemark USA, and Cinepolis, which
represent eleven scheduled installations with an opportunity to expand to as
many as twenty-three IMAX systems. In August, National Amusements, parent
company of Viacom and the sixth largest domestic exhibitor, signed an agreement
for six theatre systems with an option to expand that to as many as eighteen.
Four of these new IMAX(R) MPX(TM) systems will be installed during the fourth
quarter, demonstrating the short time frame required for an exhibitor to
retrofit an existing multiplex theatre to incorporate the IMAX MPX system. Also
in August, Cinemark, the number-three domestic operator, signed an agreement for
two IMAX systems, growing its IMAX theatre commitment from five to seven. In
September, Cinepolis, the largest exhibitor in Latin America and the eighth
largest in the world, ordered three IMAX systems, the first of which is expected
to install this Fall at Mexico City's Cinepolis Perisur multiplex, the
highest-grossing multiplex in the country.

"The IMAX commercial theatre network continues to grow, as we just completed the
best quarter in seven years in terms of signings, which serve as the best
forward indicator of our near-term growth and predictor of financial results,"
continued Messrs. Gelfond and Wechsler, "The success that many of our customers
are experiencing with IMAX DMR(R) films is leading to increased interest from
exhibitors around the world, and we have not seen this level of inquiries in
more than five years."

During the third quarter, IMAX theatres exhibited two major Hollywood
blockbuster films, both of which demonstrated the broad audience appeal and
strong box office "legs" characteristic of an IMAX DMR film. Warner Bros.
Pictures' Harry Potter and the Prisoner of Azkaban: The IMAX Experience and
Spider-Man 2: The IMAX Experience from Sony's Columbia Pictures, which became
the fourth major Hollywood studio to release an event film in IMAX's format,
shared screen-time throughout the summer, generating a strong combined box
office for commercial exhibitors.

Also during the quarter, IMAX and Warner Bros. Pictures announced that they
would jointly produce their second original IMAX(R) 3D film, Denizens of the
Deep, for release in 2006. This is Warner Bros. Pictures' sixth film commitment
to IMAX theatres in just the past 18 months, and follows on the heels of NASCAR
3D: The IMAX Experience, a film that has already grossed more than $19 million.


                                                                           .../3

In just two weeks, on November 10, IMAX will release the much-anticipated 3D
version of Warner Bros. Pictures' major holiday film, The Polar Express. The 3D
IMAX DMR version of this Robert Zemeckis film, based on the classic children's
book and starring Tom Hanks, will open day-and-date, or simultaneously, with the
film's 35mm 2D release, and marks the first-ever release of a full-length
Hollywood event film in the unparalleled IMAX 3D format.

"A proven 'win' at the box office and with consumers, Hollywood event films
converted to IMAX's format are helping to drive the top-line results sought by
commercial exhibitors to generate strong financial returns on their IMAX
systems," concluded Messrs. Gelfond and Wechsler. "We are pleased with the
performance of our summer event films and look forward to the day-and-date
release of The Polar Express, the first-ever Hollywood feature film in IMAX 3D.
We expect consumer reaction and recent box office successes to continue to
accelerate our ongoing discussions with other major studios and believe that
2005 will be our best year ever for Hollywood films in IMAX theatres."

For the nine-month period ended September 30, 2004, the Company's consolidated
revenues were $88.5 million as compared to $89.3 million in the prior year
period. Systems revenue was $57.8 million versus $55.9 million in the prior year
period, with the Company recognizing revenue on thirteen theatre systems versus
fifteen theatre systems in the year-ago period. Film revenue was $17.2 million,
as compared to $19.6 million for the nine months ended September 30, 2003.
Theatre operations revenue was $11.2 million for the nine months ended September
30, 2004, as compared to $10.1 million in the same period last year. Other
revenues were $2.3 million, as compared to $3.7 million in the same period last
year. The Company reported net earnings of $0.06 per diluted share for the nine
months ended September 30, 2004, as compared to net earnings of $0.02 per
diluted share for the prior year period.

The Company will host a conference call to discuss these results at 10:30 AM ET.
